Configuring Your ReadyNAS for Flex-RAID

By dbott | October 6, 2010

By default, the ReadyNAS configures itself using X-RAID. X-RAID is Netgear’s eXpandable RAID technology that allows you to expand the size of your hard drive both horizontally (by adding more drives) and vertically (by replacing smaller drives with larger drives). In the event that you wish to configure your ReadyNAS for another RAID level, such as RAID 0, 1, 5* or 6**, you’ll need to perform a factory default and during the 10-minute setup window select Flex-RAID as the RAID type using RAIDar.
* Requires a ReadyNAS with at least 4-bays and at least 3 drives installed.
** Requires a ReadyNAS with at least 6-bays and at least 4 drives installed.


  1. Install RAIDar on your computer
  2. After testing and installing your drives into the ReadyNAS, connect the NAS to the network and power it on.
  3. On your computer, run the RAIDar discovery tool and scan for your ReadyNAS before 10-minutes expires, otherwise the NAS will default to X-RAID mode
  4. Once the NAS has been discovered you can select your desired RAID level:
  5. After selecting Flex-RAID, the system will create a RAID 1 volume automatically. You need to delete the existing volume first:
  6. Once that’s done, you should be able to select which type of RAID array you wish to create, as well as which drives it should be created on:
  7. After creating the volume, you will be prompted to restart the device before the volume is added:

    If you’ve already put data on it & the RAID level is X-RAID, you’ll need to backup your data & start again.

    Thanks a lot for this post: I spent an hour wondering why I wasn’t able to delete a volume :-)
